Hi Yves,
From the pictures only would be my favorite the Maguindanao blade.
A restoration in the Philippines will be much cheaper as in Europe or the States!
And Milandro is correct, it's easier to find an antique Moro weapon in the States than in the Philippines.
It's in the meanwhile the same with Indonesian blades, you find more in Europe as in Indonesia.
And for sure a restoration is a good investment, look how good examples in this time frame got sold by auctions as well by epray.
When the blade is good like my one from this time it is worth given it clothings.
Regards,
Detlef
